Radial extensions in fractional Sobolev spaces

Haim Brezis, Petru Mironescu, Itai Shafrir

Given $f : \partial (- 1, 1)^{n} \to R$ , consider its radial extension $T f (X) := f (X /∥ X ∥_{\infty})$ , $\forall X \in [- 1, 1]^{n} ∖ {0}$ . In "On some questions of topology fo…

Distances between homotopy classes of $W^{s, p} (S^{N}; S^{N})$

Haim Brezis, Petru Mironescu, Itai Shafrir

We introduce an equivalence relation on $W^{s, p} (S^{N}; S^{N})$ involving the topological degree, and we evaluate the distances (in the usual sense and in the Hausdo…
